Harold had made a profound impact on the scientific careers and personal growth of many of us. As an excellent researcher, thoughtful supervisor, active education director and head of the astrophysics lab, he was a key member of the astrochemical community at Leiden Observatory. To celebrate his career and scientific achievements, a symposium is being organised in his honour. We hope many of his friends and colleagues can attend and pay tribute to his legacy.
